phpMyAdmin has quite a lot of configuration settings, those are described in
设置. There are several layers of the configuration.

The global settings can be configured in config.inc.php as described in
设置. This is only way to configure connections to databases and other
system wide settings.

On top of this there are user settings which can be persistently stored in
phpMyAdmin 高级功能, possibly automatically configured through
Zero configuration. If the phpMyAdmin 高级功能 are not configured, the settings
are temporarily stored in the session data, these are valid only until you
logout.

You can also save the user configuration for further use, either download them
as a file or to the browser local storage. You can find both those options in
the Settings tab. The settings stored in browser local storage will
be automatically offered for loading upon your login to phpMyAdmin.
